Abstract:

Oligochaeta assemblages are important components in freshwater environments, where their abundance and composition may indicate aspects related to water quality and sediment. The lack of information about these communities in Brazilian aquatic environments, as well as the application of native species as bioindicators of lotic environmental, stimulated the conception of this paper. Thus, the aim was to study the community of aquatic Oligochaeta in selected stretches of the Juruena River (MT), thereby generating grounds for future environmental monitoring action in lotic ecosystems. For this purpose, samples were analyzed at bimonthly intervals during the period from January to November 2009, in stretches of the Juruena River (Amazon River Basin) located in the State of Mato Grosso (MT). Two methods were used to collect the organisms: a) "D" network in small clusters of fixed macrophytes in the sediment on the river banks; and b) Ekman-Birge dredge in fine sediment. Preliminary results were 584 organisms distributed in 22 taxa. Of these, 22 valid species were identified. This number corresponds to approximately 25% of the aquatic oligochaete species registered in Brazil. Of these species, Limnodrilus hoffmeisteri, Dero nivea and Pristina rosea can be associated with organic enrichment conditions and/or some level of environmental degradation.

Resumo:

Comunidades de oligoquetos constituem importante componente em ambientes de água doce, onde sua abundância e composição podem indicar aspectos relacionados à qualidade da água e do sedimento. A carência de informações sobre estas comunidades em ambientes aquáticos brasileiros, bem como a aplicação de espécies nativas como bioindicadores de ambientes lóticos estimularam o desenvolvimento do presente trabalho. Assim, o objetivo foi estudar a comunidade de oligoquetos aquáticos em trechos selecionados do Rio Juruena (MT), gerando subsídios para futuras ações de monitoramento ambiental em ecossistemas lóticos. Métodos: Para isso foram analisadas amostras efetuadas em intervalos bimestrais durante o período de janeiro a novembro 2009, em trechos do Rio Juruena (Bacia Hidrográfica do Rio Amazonas) localizado no Estado de Mato Grosso (MT). Para coleta dos organismos foram utilizados dois métodos: a) rede em "D" em pequenos agrupamentos de macrófitas fixas no sedimento nas margens do rio; e b) draga Ekman-Birge em sedimento arenoso. Os resultados preliminares 584 organismos distribuídos em 22 táxons. Dentre estes, foram identificadas 22 espécies válidas. Esse número corresponde aproximadamente 25% das espécies de oligoquetos aquáticos registradas no Brasil. Destas espécies, Limnodrilus hoffmeisteri, Dero nivea e Pristina rosea podem ser associadas à condições de enriquecimento orgânico e/ou algum nível de degradação ambiental.

Introduction

Oligochaeta are some of the most abundant groups in continental aquatic macrofauna and play an important role in the process of decomposition and cycling of organic matter in freshwater ecosystems (Ragonha & Takeda, 2014RAGONHA, F.H. & TAKEDA, A. M. 2014. Does richness of Oligochaeta (Annelida) follows a linear distribution with habitat structural heterogenety in aquatic sediments? J. Limnol. 73 (1): 146-156., Cesar & Henry 2017CESAR, D. A. S. & HENRY, R. 2017. Is similar the distribution of Chironomidae (Diptera) and Oligochaeta (Annelida, Clitellata) in a river and a lateral fluvial area? Acta Limnol. Bras. 29 (8).). These organisms are found in almost all fresh aquatic environments (Cesar & Henry 2017CESAR, D. A. S. & HENRY, R. 2017. Is similar the distribution of Chironomidae (Diptera) and Oligochaeta (Annelida, Clitellata) in a river and a lateral fluvial area? Acta Limnol. Bras. 29 (8).), living in sediment and water columns (Rodriguez & Reynoldson 2011RODRIGUEZ, P. & REYNOLDSON, T.B. 2011. The Pollution Biology of Aquatic Oligochaetes. Ed. Springer Science, London.), and in association with other organisms (Corbi et al. 2004CORBI, J.J., JANCSO, M.A., TRIVINHO-STRIXINO, S. & FRAGOSO, E.N. 2004. Occurence of Oligochaeta living on larvae of Odonata from Ipeúna (São Paulo state, Brazil. Biota Neotrop. 4 (2): 1-3., Alves & Gorni 2007ALVES, R.G. & GORNI, G.R. 2007.

Biol. 75 (1): 86-90.).

In addition, these worms have limited mobility and are influenced by the habitat characteristics in which they are found (Behrend et al. 2012BEHREND, R.D.L., TAKEDA, A.M., GOMES, L.C. & FERNANDES, S.E.P. 2012. Using Oligochaeta assemblages as na indicator of environmental changes. Braz. J. Biol. 72 (4), 873-884.). Thus, the richness and abundance of Oligochaeta is directly related to environmental variables (Marchese & Drago 1999MARCHESE, M. & DRAGO, I.E. 1999. Use of benthic macroinvertebrates as organic pollution indicators in lotic environments of Paraná River drainage basin. Pol. Arch. Hydrobiol. 46 (3-4): 233-255., Jablonska, 2014JABLONSKA, A. 2014. Oligochaete communities of highly degraded urban streams in Poland, Central Europe. North-West. J. Zool. 10 (1): 74-82,), such as availability of food resources (Martins & Silveira, Alves 2011MARTINS, R.T., SILVEIRA, L.S. & ALVES, R.G.. 2011. Colonization by oligochaetes (Annelida: Clitellata) in decomposing leaves of Eichhornia azurea (SW.) Kunth (Pontederiaceae) in a neotropical lentic system. Ann. Limnol. 47: 339-346.); dissolved oxygen (Dornfeld et al. 2006DORNFELD, C.B., ALVES, R.G., LEITE, M.A. & ESPÍNDOLA, E.L.G. 2006. Oligochaeta in eutrofic reservoir: the case of Salto Grande reservoir and their main affluent (Americana, São Paulo, Brazil). Acta Limnol. Bras. 18 (2): 189-197.); type of substrate (Moretto et al. 2013MORETTO, Y.; SIMÕES, N.R.; BENEDITO, E. & HIGUTI, J. 2013. Effect of trophic status and sediment particle size on diversity and abundance of aquatic Oligochaeta (Annelida) in neotropical reservoirs. Ann. Limnol. 49 (1): 65-78.); water temperature (Nascimento & Alves 2009NASCIMENTO, H.L.S. & ALVES, R.G. 2009. The effect of temperature on the reproduction of Limnodrilus hoffmeisteri (Oligochaeta: Tubificidae). Zoologia 26 (1): 191-193,), thus being considered indicators of specific habitats.

However, although common in freshwater environments (Timm et al. 2001TIMM, T.; SEIRE, A.; PALL, P. 2001. Half a century of oligochaete research in Estonian running waters. Hydrobiologia 463: 223-234.), knowledge about Oligochaeta fauna in Brazilian fresh waters is still fragmented and incomplete (Alves et al. 2008ALVES, R.G.; MARCHESE, M.R. & MARTINS, R.T. 2008. Oligochaeta (Annelida, Clitellata) of lotic environments at Parque Estadual Intervales (São Paulo, Brazil). Biota Neotrop. 8 (1): 69-72., Takeda et al. 2017TAKEDA, A. M., FUJITA, D. S., RAGONHA, F.H., PETSCH, D.K. & MONTANHOLI-MARTINS, M.C. 2017. Oligochaeta (Annelida) de ambientes aquáticos continentais do Estado do Mato Grosso do Sul (Brasil) , Iheringia, Sér. Zool. 107: 1-5.). This lacuna is mainly due to the concentration of studies related to the spatial distribution of benthic invertebrate fauna, with emphasis on insect larvae (Roque & Trivinho-Strixino 2001ROQUE F.O. & TRIVINHO-STRIXINO, S. 2001. Benthic macroinvertebrates in mesohabitats of diferent spatial dimensions in a first order stream. Acta Limnol. Bras. 13: 69-77., Sanseverino & Nessimian, 2001SANSEVERINO, A.M. & NESSIMIAN, J.L. 2001. Hábitats de larvas de Chironomidae (Insecta, Diptera) em riachos de Mata Atlântica no Estado do Rio de Janeiro. Acta Limnol. Bras. 13: 29-38.), the great extent of the still unexplored parts of the Brazilian hydrographic basins (Joly et al. 2011JOLY, C. A., HADDAD, C. B., VERDADE, L., OLIVEIRA, M. C., BOLZANI, V. S. & BERLINCK, R. 2011. Diagnóstico da pesquisa em biodiversidade no Brasil. Revista USP 89, 114-133.) and the low financial investment in scientific research in the country (Agostinho et al. 2005AGOSTINHO, A. A., THOMAZ, S.M. & GOMES, L.C. 2005. Conservação da biodiversidade em águas continentais do Brasil. Megadiversidade 1 (1): 70-78., Magurran 2011MAGURRAN, A. E. 2011. Medindo a diversidade biológica. Editora UFPR, Paraná.).

However, since the 1980s, taxonomic identification keys developed specifically for South America (Brinkhurst & Marchese 1989BRINKHURST, R.O. & MARCHESE, M.R. 1989. Guia para la indentificacion de Oligoquetos aquáticos continentales de Sud y Centroamerica. Asociación de Ciencias Naturales del Litoral, Santa Fé.) and Brazil (Righi 1984RIGHI, G. 1984. Manual de identificação de invertebrados límnicos do Brasil. CNpq/Coordenação Editorial, Brasília.) encouraged new research on the Oligochaeta, addressing aspects of their ecology (Petsch et al. 2015PETSCH, D.K.; RAGONHA, F.H.; GIMENEZ, B.C.G.; BARBOZA, L.G.A. & TAKEDA, A.M. 2015. Partitioning beta diversity of aquatic Oligochaeta in different environments of a Neotropical floodplain. Acta Sci. Biol. Sci. 37 (1): 41., Rodrigues et al. 2016RODRIGUES, L. F. T.; LEITE, F. S. & ALVES, R. G. 2016. Influence of bryophyte biomass and organic matter quantity on the abundance and richness of oligochaetes in forest streams with different phytophysiognomies in southeastern Brazil. J. Limnol. 75 (2): 340-346.), their geographic distribution (Gorni & Alves, 2008GORNI, G. R. & ALVES, R.G. 2008a. Naididae species (Annelida: Oligochaeta) associated with the sponge Metania spinata (Carter, 1881) (Porifera: Metaniidae) from a southeastern reservoir. Acta Limnol. Bras. 20 (3): 261-263., Gomes et al. 2017GOMES, D. F., SANCHES, N. A. O., SAHM, L. H. & GORNI, G. R. 2017. Aquatic oligochaeta (Annelida: Clitellata) in extractive reserve Lake Cuniã, Western Brazilian Amazon. Biota Neotrop. 17 (1): 1-7.), their composition in anthropologically disturbed environments (Behrend et al. 2012BEHREND, R.D.L., TAKEDA, A.M., GOMES, L.C. & FERNANDES, S.E.P. 2012. Using Oligochaeta assemblages as na indicator of environmental changes. Braz. J. Biol. 72 (4), 873-884., Rosa et al. 2014ROSA, B.J.F.V.; RODRIGUES, L.F.T.; OLIVEIRA, G.S. & ALVES, R.G. 2014. Chironomidae and Oligochaeta for water quality evaluation in an urban river in southeastern Brazil. Environ Monit Assess. 186 (11): 7771-7779.) and their use as test organisms in ecotoxicological experiments (Corbi et al. 2015CORBI, J.J., GORNI, G.R. & CORREA, R.C. 2015. An evaluation of Allonais inaequalis Stephenson, 1911 (Oligochaeta: Naididae) as a toxicity test organism. Ecotoxicol. Environ. Contam. 10 (1): 7-11., Lobo & Espindola 2016LOBO, H. & ESPÍNDOLA, E. L. G. 2016. Branchiura sowerbyi reared in two sediments for ecotoxicological bioassays, Ecotoxicol. Environ. Contam. 11 (1): 11-14.).

However, the lack of information about these organisms in Brazilian aquatic environments is still evident in many regions (Gomes et al. 2017GOMES, D. F., SANCHES, N. A. O., SAHM, L. H. & GORNI, G. R. 2017. Aquatic oligochaeta (Annelida: Clitellata) in extractive reserve Lake Cuniã, Western Brazilian Amazon. Biota Neotrop. 17 (1): 1-7.), as well as the use of native species as bioindicators of the quality of the country's aquatic ecosystems. Thus, the main objective of this paper was to study the aquatic Oligochaeta community in selected stretches of the Juruena River (MT), providing information for future action of environmental monitoring in lotic ecosystems.

Material and Methods

1. Study area

For the analysis of the Oligochaeta assemblages, samples were analyzed at bimonthly intervals during the period from January to November 2009. For the regular samplings, five sites were selected from the Juruena River (Amazon River Basin), located in the State of Mato Grosso (MT) (Figure 1).

Figure 1
Map showing the location of the study area with highlight of the sampled section.

The region is demarcated by humid tropical climates to contrasting seasons. Regionally the rainy season has its beginning, usually in the month of September until the month of April. From December to March are characterized by a increase in regional rainfall (Tardy, 1986TARDY, Y. 1986. Le Cycle de L'Eau - Climats, Paleoclimats et Géochimie Globale. Masson Editeurs, 338 p, Paris, France). The basin is mainly sheltered by Ombrophilous Forest (Instituto Brasileiro de Geografia Estatística, 1992). In the upper portion of the basin, close to the Juruena, the vegetation is classified as "Cerrado". The soils in the basin are largely composed of red-yellow Acrisols (29%), red-yellow Oxisols (27%) and Arenosols (18%) (Empresa Brasileira de Pesquisa Agropecuária, 1980).

The headwaters of Rio Juruena are situated at the Parecis Plateau, in a savanna ecosystem ("cerrado"). In this area the water is totally transparent and poor in nutrients (N, P, and Ca). Biochemical oxygen demand (BOD) and fecal coliform bacteria are low, demonstrating that anthropic contributions are insignificant. Macrophytes are not abundant and are distributed in discrete and sparse stands, sometimes covering a sand plateau onshore.

The collection sites were selected considering: i) prevailing habitats, ii) easy access, and iii) adequate sites for the use of benthic fauna samplers (details of the geographical location of the sites are shown in Table 1).

Table 1

2. Data collection

The collection of organisms followed the methodology described by Dowing (1984) and Peckrasky (1984). Thus, two methods of collecting zoobenthos were used: a) the D-net sampler in small groups of fixed macrophytes on the river margin; and b) Ekman-Birge dredge in fine sediment to collected sediment and associated organisms.

The net, with 0.30 m mesh openings, was dragged 1.0 m by the macrophyte roots, making a capture area of 0.3 m2. The dredge, with an area of 0.0225 m2, was launched in locations close to the margins in depths of up to 3 m. As an adopted procedure, two samples (replicas) were made with the net and dredge at each sampling site (a total of 50 sample units). Still at the sites, the collected samples were washed in a sieve with a mesh of 0.21 mm opening, fixed in 10% formalin and preserved in 70% alcohol. In the laboratory, the samples were washed again on a 0.021mm mesh granulometric sieve. The organisms were screened in a WILD® stereomicroscope with a maximal increase of 30 times.

For the identification of Oligochaeta, taxonomic criteria adopted by Brinkhurst & Jamieson (1971)BRINKHURST, R.O. & JAMIESON, B.G.M. 1971. Aquatic Oligochaeta of the world. University of Toronto Press, Toronto., Righi (1984)RIGHI, G. 1984. Manual de identificação de invertebrados límnicos do Brasil. CNpq/Coordenação Editorial, Brasília., Brinkhurst & Marchese (1989)BRINKHURST, R.O. & MARCHESE, M.R. 1989. Guia para la indentificacion de Oligoquetos aquáticos continentales de Sud y Centroamerica.

A guide to the freshwater Oligochaeta and Polychaeta of Northern and Central Europe. Lauterbornia 66: 1-235. were followed. The list of species in synonymy was based on the catalog proposed by Christoffersen (2007)CHRISTOFFERSEN, M.L. 2007. A catalogue of aquatic microdrile oligochaetes (Annelida: Clitellata) from South America. Acta Hydrobiol Sin. 31, 59-86..

All biological material identified was deposited in the Laboratory of Ecology and Aquatic Ecotoxicology (LEEA) linked to the Department of Hydraulics and Sanitation, School of Engineering of São Carlos, University of São Paulo.

In order to verify the sensitivity of the species to the different habitats, fixed macrophytes, mainly Podostemacean species on the river margin (collected with a D-net sampler) and fine sediment (Ekman-Birge dredge) we applied Indicator Species Analysis (ISA) (Dufrene & Legendre, 1997DUFRÊNE, M. & P. LEGENDRE. 1997. Species assemblages and indicator species: the need for a flexible asymmetrical approach. Ecol Monogr. 67: 345-366.) (alpha = 0.05). This analysis combines species relative abundance with their relative frequency of occurrence in the various groups of samplers. This analysis was made using the ''indicspecies'' package (De Caceres & Legendre, 2009DE CACERES, M. & LEGENDRE, P. 2009. Associations between species and groups of sites: indices and statistical inference. Ecology 90 (12): 3566-3574.) in R software (R Core Team, 2017R CORE TEAM. 2017. R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. http://www.R-project.org/ (last access in 19/04/2018)
http://www.R-project.org/...
), with 10,000 permutations.

Results

A total of 584 organisms were identified in 22 valid species comprising 11 genera. This number corresponds to less than 1% of the aquatic species described in the world and approximately 1/4 of the species registered in Brazil (Christoffersen 2007CHRISTOFFERSEN, M.L. 2007. A catalogue of aquatic microdrile oligochaetes (Annelida: Clitellata) from South America. Acta Hydrobiol Sin. 31, 59-86., Martin et al. 2008MARTINS, R.T. & ALVES, R.G. 2008. Occurrence of Naididae (Annelida: Oligochaeta) from three gastropod species in irrigation fields in southeastern Brazil. Biota Neotrop. 8 (3): 255-257.). The relative abundance of the Oligochaeta species are shown in Table 1. The specie Brinkhurstia americana showed a relative abundance greater than 50% of the total fauna in all the points sampled.

The Indicator Species Analysis (ISA) reveals five indicator species of fixed macrophytes (Aulophorus costatus, Dero pectinata, Dero digitata, Dero sawayai and Dero nivea), and four indicator species from fine sediment (Aulodrilus pigueti, Limnodrilus hoffmeisteri, Aulophorus lodeni and Narapa bonetoi) (Table 2).

Based on species distribution patterns and habitat preference (ISA) in the Juruena River, we concluded that Dero species are associated with marginal regions of aquatic ecosystems, mainly occurring as aquatic macrophytes. This condition demonstrates the susceptibility of this species group to samplers such as D-net. Limnodrilus hoffmeisteri, Aulodrilus pigueti, Narapa bonettoi and Aulophorus lodeni were related with depositional zones, where fine sediments occur. L. hoffmeisteri are also registered as being associated to organic enrichment conditions and/or some degree of environmental degradation.

Thus, in order to increase the efficiency of future environmental quality monitoring programs carried out in the region, cautious monitoring of these species in other parts of the Amazon River Basin is advisable.
